Statements uttered regarding Islamic rulings

Aslaamualaikum
Jazakallah for the reply to the last question ID : 19895 (copied and pasted below). I have a question about it.
The second part where you have said:
‘But if he thinks and believes that Allaah has given a ‘hard’ Shariah then it will tantamount to Kufr.’
Does this mean the Muslim has left the fold of Islam?
Jazakallah

Dear Mufti Sahib. Please shed some light on the following.

1) if a Muslim verbally says: ‘following all rules and rulings of Islam is too hard or gets too hard or following rules of Islam properly is too hard or some rules of Islam are too hard.’

Does the above verbal sayings cause kufr?

Jazakalah khairan
Answer:
Perhaps he means due to his physical disposition at times, he feels so, then no Kufr.
But if he thinks and believes that Allaah has given a ‘hard’ Shariah then it will tantamount to Kufr.
